Abstract

The object of the present invention is to provide a liquid developing agent for electrophotography or electrostatic recording obtained by utilizing the coacervation method, wherein such liquid developing agent has good abrasion resistance. To this end, a liquid developing agent is provided which is obtained by utilizing the coacervation method, comprising insulating liquid in which colored resin particles formed by at least pigment, pigment dispersant, acid-group-containing resin, binder resin, and resin whose glass transition temperature is −120 to −60° C. are dispersed, wherein the resin whose glass transition temperature is −120 to −60° C. is contained in the colored resin particle by 1.0 to 5.0 percent by mass.
